COAL-STOV.

The Schedule referred to in these Letters Patent and making part of the same.

To all/whom it may ,concern Be it known that I, NATHAMEL Kersen, of Newton, in the county of Jasper, and in the State oflowa, have invented certain new and useful Improvements in Stoves; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in providing a stove, with a pipe passing from rear to front, inside of the same, said pipe having one o r more outletpipes, or tubes through the top of, the stove, for the purpose of heating the same, or any other room, by means of the air, which, while passing through said pipes, becomes thoroughly heated from the re in the stove.A

In order to enable others skilled in the art to which my invention appertains, to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, which form a part of this specification, and in which- Figure 1 is a longitudinal vertical section, and

Figure 2 is a front elevation.

A represents a stove, of any size and shape;

B is the ash-box; and

O, the grate.

y Through the centre of the stove A is placed a tapering pipe, D, which passes from the rear to the front of the stove, the rear end of said pipe, which is the larger, being depressed or placed just above the rear end of the grate G,while the front end, which is the smaller, passes out about half way between the grate andthe top of the stove.

Both ends of the pipe D pass through the stove,

A, substantially as set forth.

and are open. The i'ont end may, however, be closed by a cap, as represented inthe drawings.

When a fire is lighted in the s tove, the cold air in the room willenter the lower rear end of the pipe D,"

and pass out through the upper front end, becoming v thoroughly heated in its passage through the pipe.

Thehot air rising, will crowd the cold air downward in the room, and force. it through the pipe, and

the pipe, heilig tapering, will cause a continuous cnr--` rent of air through the same.

By this means, the room may be heated with less fuel than `is ordinarily used, and by covering the pipe with coals'and ashes, the room may be kept warm during the entire night. g

To heat rooms above-the one in which the stove is placed, one or more pipes E may he placed -to lead from the pipe D, through the -top of the stove, and

`thus conduct the heated air to any point desired.

The pipes E E may be provided with dampers, as shown in red in tig. 1, to regulate the amount of hot air distributed. l

Having thus fully described my invention,

Whaty I claim as new, and desire to secure by Letters Patent, is

The arrangement of the inclined tapering pipe D, tubes E E, grate O, and ash-box B, within the stove In testimony that I claim theY foregoing, I have hereunto set my hand, this 26th day of January, 1869.
